IST to PST Converter (India Time to Pacific Time)

Mid-January 2026: PST is 13 hours 30 minutes behind IST. Mid-July 2026: PDT is 12 hours 30 minutes behind IST.

An Indian reader who needs the time in California, Seattle or Portland converts from India Standard Time (UTC+05:30) to Pacific Time. The result falls on the previous calendar day for an Indian morning and early afternoon, and on the same day for the rest of the Indian day.

Because India does not change its clocks, the offset depends on the Pacific side only. It is UTC-08:00 in winter and UTC-07:00 in summer, so a given Indian time lands an hour later on the Pacific clock after the US moves forward.

How to use this tool

1. Pick a date and time in IST. The date matters when daylight saving time is in force.
2. Read the matching time in PST, with both UTC offsets.
3. Use "Use current time" for now, or the tables below for a quick look.

Formula

PST time = IST time − (IST UTC offset) + (PST UTC offset)

The converter looks up both UTC offsets for the actual instant in the saved IANA time zone rules, so daylight saving changes are included automatically.

Example

Worked with the saved rules:

9:00 AM IST on March 2, 2026 = 7:30 PM PST (previous day)

6:30 PM IST on August 3, 2026 = 6:00 AM PDT

Time difference through the year

The difference depends on the date when either place moves its clocks. These are the offsets on two reference days, from the saved IANA rules:

Clock changes in 2026

Between these dates the difference shifts by the size of the change.

The previous day problem

Take a 10:00 a.m. IST meeting. In winter it is 8:30 p.m. PST on the previous day, and after March 8 it is 9:30 p.m. PDT, still the previous day. Indian staff who send a Friday 10:00 a.m. request are really writing for Thursday evening on the US West Coast.

That is the reason many Indian professionals who work with California use two calendars at once: the local one for their own day and a Pacific one for their counterparts.

Which Indian hours suit a Pacific call

The most convenient pairing puts an Indian evening against a Pacific morning. A 9:00 p.m. IST call is 7:30 a.m. in winter Pacific Time, which suits an early-riding California engineer, and a 10:00 p.m. IST call is 8:30 a.m. Pacific.

Indian time stays put while California clocks change, so the same Indian time falls an hour later on the Pacific clock after March 8, 2026 and an hour earlier again after November 1.
